It has the functions of anti-cold, moisturizing, anti-frost, anti-freezing, light transmission, and air regulation, and has the characteristics of light weight, convenient use, corrosion resistance, etc. Well, can also be used for multi-layer coverage.</p><p><br></p><p>Vegetable <a href="https://www.synwinchina.com/extra-wide-non-woven-fabric" rel="noopener noreferrer" target="_blank"><strong>PP agriculture non woven fabric</strong></a> can play the role of heat preservation, moisturizing, promoting seed germination, etc. It can also fertilize, water and spray on the bed surface. Not only is it convenient to use, but also the seedlings cultivated are thick and neat. Because its heat preservation, air permeability and humidity control are superior to mulch, its effect of covering seedlings is better than mulch. Agriculture non woven fabric with a specification of 20 grams or 30 grams per square meter for bed cover, and white or silver-gray in winter and spring. After sowing, the agriculture non woven fabric whose length and width are larger than the border surface is directly covered on the bed surface. Because the plant protection fleece has a certain flexibility, the length and width must be greater than the length and width of the border. It must be fixed at both ends and both sides of the border, and the edge of the cloth should be compacted with soil or stone. It can also be made of U-shaped or T-shaped curved rods made of iron wire and fixed at a certain distance. After emergence, according to weather conditions and vegetable production requirements, pay attention to cover in time, usually during the day, cover at night or cover in cold weather.</p><p><br></p><p>Covering the back of the planting compartment plays the role of heat preservation, moisturizing, promoting rooting and shortening the slow seedling period. For example, mulching in early spring can generally increase the temperature of the stratum by 1°C to 2°C, make it mature about 7 days earlier, and increase the early yield by 30% to 50%. After the melons and solanaceous vegetables are planted, water the roots thoroughly and cover them all day long. The non-woven fabric with the specification of 20 grams or 30 grams per square meter is directly covered on the plant, and the four sides are placed on the ground, and the four sides are pressed with clods or stones. Be careful not to stretch the non woven plant protection fleece too tightly, and leave room for the vegetables to have plenty of room for growth. According to the growth rate of vegetables, adjust the position of the soil block or stone in time. After the seedlings survive, determine the covering time according to the weather and temperature: when the temperature is high on sunny days, cover during the day and cover at night, and cover early and late; when the temperature is low, cover late and early, and cover all weather when the cold wave comes. The<a href="https://www.synwinchina.com/plant-cover" rel="noopener noreferrer" target="_blank"><strong> plant fleece covers</strong></a> will be removed after mid-to-late April.</p><p><br></p><p>The small arch canopy is used for early-maturing, high-yield and high-quality cultivation, and can also be used for shading and cooling seedlings in summer and autumn. For early spring covering, white non-woven plant fleece covers can be used, with a specification of more than 20 grams per square meter; for summer and autumn seedlings, silver-gray non-woven fabrics or black non-woven fabrics with specifications of 20 grams or 30 grams per square meter can be used. For example, celery in summer has high requirements for shading and cooling, and black non-woven fabrics are used. When early maturation promotes cultivation, the non-woven plant fleece covers are covered on the small arch frame, and then covered with plastic film, which can increase the temperature in the shed by 1.8 ° C ~ 2.0 ° C; when covering in summer and autumn, the darker non-woven fabric can be directly covered on the arch frame, And it does not need to be covered with plastic film or agricultural film.</p><p><br></p><p>The large and medium sheds are covered by plant fleece covers. One or two layers of non-woven fabrics with a specification of 30 grams or 50 grams per square meter are hung in the large and medium sheds as a canopy, so that a distance of 15 cm to 20 cm wide is maintained between the canopy and the shed film to form a thermal insulation. Layer, which is beneficial to seedling raising, cultivation in winter and spring, and postponing cultivation in autumn, and can generally increase the ground temperature by 3 °C to 5 °C. Open the sky during the day, close the sky at night, and close without leaving any gaps. The canopy is closed during the day in summer and opened at night, which can cool the temperature and facilitate seedling cultivation in summer. Overwintering vegetables in the open field are covered for heat preservation. The open field cultivation is covered with non-woven fabrics, and the heat preservation effect is more obvious than that in the greenhouse. It can be used for celery, lettuce, spinach, shepherd's purse and bean sprouts, etc., to prevent freezing injury, promote growth, improve quality, and be marketed earlier. Covered with a plant protection fleece with a specification of 30 grams per square meter, the cover can be opened day and night, and it can be put on the market 10 to 20 days earlier, with an increase of more than 20%.</p><p><br></p><p>Synwin is a professional <a href="https://www.synwinchina.com/" rel="noopener noreferrer" target="_blank"><strong>agriculture non woven fabric suppliers</strong></a>, specialized in high quality plant fleece covers, plant protection fleece and pp agricultural nonwoven fabric, welcome to contact!</p>
